Production of Time Intervals by Aged Subjects

Characteristics of time perception by aged subjects of both sexes aged 60–91 years were studied. They assessed time intervals of 1, 3, 5, 7, and 10 s. It was found that the 1-s interval is significantly overestimated, while the other intervals are underestimated. The maximum error in time measurement was found in women. The subjective time scale in aged subjects is more narrow than the physical scale, and the value of the psychophysical measurement function is significantly smaller than unity (p 0.05).
